EVEC-Engineered Polyurethane Foam
EVEC-Engineered Polyurethane Foam, developed by Qingdao Chooyu Advanced Material Co., Ltd. using Ecombine's Ecomseal product, is an innovative noise-reduction solution for automotive tires. This PU Foam is manufactured from specialized polymer materials featuring a porous structure. When air vibrations penetrate the material, friction generated against the pore walls effectively attenuates vibrations, achieving significant noise reduction.
